PEN ATTACHMENT.

SPECIFICATION formingpart of Letters Patent N 0. 678,909, dated July 23, 190] Application filed March 11, 1901. Serial No. 50,718- (No model.)

To all whom, it may concern: v

Be it known that I, BELON B. SMITH, a citizen of the United States, residing at Pensacola, in the county of Escambia and State of Florida, have invented a new and useful Pen Attachment, of which the following is aspecification.

This invention relates to pen attachments, and refers particularly to fountain-reservoir auxiliaries which are applied to the penpoints; and the object of the present device is to improve this class of attachments and render them more positive and efiective in their use and make them serve as reliable fountains for inkand prevent blotting by overflow and applicable to any form of penpoint without materially changing the construction of the same.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a pen-point, showing the improved attachment applied thereto. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a detail perspective view of a pen point arranged to receive the improved attachment. Fig. 4 is a detail perspective view of the main part of the attachment.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a pen-point of any preferred form of construction and provided with the usual nibs 2 and securingshank 8 of concavo-convex form, the latter having at an intermediate point a tongue 4 cut therefrom and bent downwardly and slightly curved, as shown by Fig. 2.

The attachment comprises a fountain 5 of dished form and having a convergence toward the front end, the bearing edge 6, which contacts with the inner portion of the penpoint nibs, being flat and smooth for close engagement. The outer portion of the fountain is convex within the longitudinal contour of the same, and the inner side is fully open except a cross-bridge 7, which stands outward beyond the plane of the bearing edge at the rear extremity. Directly opposite said bridge in the outer side of the fountain an inwardly-directed retaining-tongue 8 is formed, and between the bridge and said latter tongue the secured head end of a bunch 9 of bristles or strand-feeders is mounted and held within the fountain thereby against accidental displacement. These bristles are arranged in the form shown and are of sufficient thickness and stiffness to remain disconnected from each other to form channels for the ink, and they have a much greater affinity for a fluid and power of capillary attraction than any metallic material. The bristles have no tendency to become clogged with deposits and can be rinsed perfectly clean after use. The bristles, while permitting a sufficiently free flow of ink from the pen by the attractive action of the flow itself, have such power of capillary attraction that a large quantity of ink can be maintained and contained in the pen without danger of dripping or flowing too rapidly to the point.

Instead of the bristles it is proposed at times to use a rubber feeder or controller that will be formed or provided with longitudinal grooves and held at the rear end similarly to the bristles.

In assembling the improved fountain attachment and pen-point the tongue 4 of the latter is pushed under the bridge 7 of the former, as clearly shown by Fig. 2, and a firm securement results, the tongue extremity also engaging the rear end of the bunch of bristles or controller, and thereby addingto the securing means of the latter.

From the foregoing it will be seen that the fountain attachment can be easily applied and quickly detached, and as the tongue 4 is yielding, in view of its formation integral with the pen-point and consequently com posed of steel or analogous resilient material, the frictional engagement set up between the same and the bridge will be very positive in retaining the attachment in place, but giving sufficiently to render the detachment of the fountain readily acquirable.

The preferred form of the improved device has been shown and described; but it is obvious that changes in the form, size, proportions, and minor details may be resorted to Without-departing from the'principle' of the invention. 5

Having thus described the invention, what is claimed as new is 1. The combination of a pen-point having an inwardly-bent y ldin on e, a foun ain attachment having a bridge thereover at its inner rear extremity under which said tongue is adapted to slip, the said bridge also formed with an inwardly-bent tongue in its own structure and which is directed inwardly from the outer side ther'e0f,and an ink -fiow-controll in device held within the attachment.

2. The combination of a pen-point having an inwardly-bent yielding tongue, a fountain '1 1'21, X .2, 1.)! 1. iii I- ,1
